(2008)Technical Description, Immature Stages: None                                                                                 
Adult Markings: Virbia ferruginosa is one of several small brownish- or yellowish-orange Virbias, all of which may be difficult to distinguish, particularly based on photographs alone, especially shots showing just the forewings. Ferruginosa is particularly similar to aurantiaca, but it larger and usually has the dark band on the hindwing broken into a series of spots; in aurantiaca, this bar is usually more solid (Zaspel et al., 2008). Females may have white spots on the forewing. Dissection offers the most reliable way of identification, at least for males (see Forbes, 1960; and Zaspel et al., 2008 for illustrations and descriptions).
Forewing Length: 13.4 mm, males; 15 mm, females (Zaspel et al., 2008)
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
Immatures and Development: Larval descriptions appear to be unavailable.
